What other things you will be doing during GSoC (vacation, exams, travel, ???)

Please be sure that you communicate your GSoC participation - including the full timeline - with your professors and any other folks who will have an interest in how you spend your time.
GSoC will very likely take more of your time and attention than you expect, and if you over-commit you will very likely fail at least one of your efforts.
You probably don't want that to happen.
We certainly don't want that to happen.

If you are a student who would like to work on a project (either one you see here, on one of or one you think of), please speak up! It would help if we could see what sort of work you can do. An easy way to show us is to find an open bug report, fix it, and submit the patch. There are project developers who are happy to work with you and help you to do this.
